Product type-description:
BR heavy duty petrochemical process pump is a horizontal and radial split centrifugal pump with single-stage, two-stage or three-stage support at both ends. It is designed according to the requirements of API610 standard and BB2 pump. Its basic type is single-stage structure, and the impeller is divided into double suction and single suction. This series of pumps are designed in strict accordance with the standards in terms of pump support, bearing arrangement, reserved interface, cooling and flushing, cavity structure, etc. Make reasonable planning, enhance the universality of parts, and reduce the types, quantity and maintenance time of spare parts.

1. According to the power and speed, the rolling bearing, sliding bearing or forced lubrication bearing structure can be configured to ensure the safe and reliable operation of the pump.

2. The rigid shaft is designed with small deflection and stable operation. The conical shaft extension meeting the requirements of API610 standard makes the installation and disassembly of coupling, bearing and seal convenient and easy to maintain.

3. The size of the sealing cavity conforms to api682 standard, and various sealing forms can be configured according to requirements.

4. The pump cover and impeller are equipped with wear-resistant sealing ring. The clearance and hardness of the sealing ring meet the requirements of API610 standard, with long service life and convenient replacement and maintenance.

5. The impeller has single-stage double suction and single-stage single suction. Double suction structure is adopted, with good cavitation performance and no hydraulic axial force. It can be used under various high and low pressure conditions to ensure the service life of the bearing.

6. The inlet and outlet flanges are designed according to GB, and can also implement ans, Hg, SH, DIN and EN standards according to user requirements. The inlet and outlet are in and out.

7. The br single-stage structure pump body has a low-pressure design pressure of 5.0mpa and a high-pressure design pressure of 11.0mpa. It adopts a double volute structure to balance the radial force well and has little impact on the pump shaft and bearing.

8. The pump cover is designed with rigidity, strong pressure bearing capacity and high reliability. It is designed with a water-cooling chamber. Under high temperature conditions, the temperature of the sealing chamber can be reduced to ensure the reliable operation of the mechanical seal.

9. Labyrinth dust disc and mechanical oil seal are optional. It can effectively prevent the dust from entering the box to damage the bearing, prevent the leakage of lubricating oil and improve the service life of the bearing.

4. The pump cover and impeller are equipped with wear-resistant sealing ring. The clearance and hardness of the sealing ring meet the requirements of API610 standard, with long service life and convenient replacement and maintenance.

5. The impeller has the first stage double suction and the second stage single suction structure, with good cavitation performance. The secondary impeller adopts the rear sealing ring and balance hole to balance the axial force without hydraulic axial force. It can be used under various high and low pressure conditions to ensure the service life of the bearing.

6. The inlet and outlet flanges are designed according to GB, and can also implement ans, Hg, SH, DIN and EN standards according to user requirements. The inlet and outlet have upper inlet and upper outlet.

7. Br type two-stage structure, with low-pressure design pressure of 11.0mpa and high-pressure design pressure of 15.0mpa, adopts double volute structure, which can well balance radial force and has little impact on pump shaft and bearing. The symmetrical space transition flow channel reduces the impact loss, so as to ensure the inlet performance of the secondary impeller and improve the efficiency.

8. The interstage bushing structure is adopted between the stages, which effectively reduces the interstage leakage, reduces the volume loss of the pump, improves the efficiency of the pump, maintains the low pressure of the sealing cavity and ensures the safe operation of the seal.

9. The pump cover is designed with rigidity, strong pressure bearing capacity and high reliability. It is designed with a water-cooling chamber. Under high temperature conditions, the temperature of the sealing chamber can be reduced to ensure the reliable operation of the mechanical seal.

10. Labyrinth dust disc and mechanical oil seal are optional. It can effectively prevent the dust from entering the box to damage the bearing, prevent the leakage of lubricating oil and improve the service life of the bearing.
